PERIOD COVERED: 0000Z (UTC) 07/31/97 - 0000Z (UTC) 08/01/97
Daily Status Report as of 213/0000Z
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed Three Sets of WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental
Darks PT1/3)
The WF/PC-2 was used to make supplemental dark calibration images.
This set of dark calibrations is intended to obtain three dark frames every
day to provide data for monitoring and characterizing the evolution of hot
pixels. The observations were executed as scheduled, and no anomalies were
noted.
1.2 Completed STIS/CCD 7659 (Daily Darks to Update Acquisition Bad Pixel
Table)
The Space Telescope Imaging Spectrograph was used to make dark
calibration images in order to update the acquisition bad pixel table.
Daily hot pixel lists can also be used for science data analysis. The
observations were executed as scheduled, and no anomalies were noted.
1.3 Completed Three Sets of NIC/3 7780 (NICMOS Short One Orbit Parallel
- Camera 3 Focus Test)
The Near Infrared Camera (Camera Three) was used to conduct a short
one orbit focus test which was conducted in parallel with the prime science
observations. The observations were completed as scheduled, and no
anomalies were noted.
1.4 Completed Four Sets of STIS/CCD 7601 (CCD Dark and Bias Monitor)
The Space Telescope Imaging Spectrograph (CCD) was used to conduct
bias and dark monitoring. Also, observations were made to track the growth
of hot pixels on the CCD in general and within the various target
acquisition apertures specifically. The observations were completed as
planned, and no anomalies were reported.
1.5 Completed NIC/2 7420 (A Near-Infrared Search for Very Low Mass
Companions to Stars Within 10 Parsecs of the Sun)
The Near Infrared Camera (Camera Two) was used to make searching
observations for very low mass companions to variable star LHS288. This
star is known to be within 10 parsecs of the Sun. The observations were
executed as scheduled, and no anomalies were noted.
1.6 Completed NIC/1/2/3 7328 (High Resolution IR Imaging Survey (IRIS)
of the Centers of the Nearest Active Galaxies)
The Near Infrared Camera (Camera One, Two and Three) was used to
make high resolution infrared observations of the nearest active galaxy
Markarian UM625 in order to study its inner nuclear region. Observing in
the near-IR minimizes the dust obstruction and maximizes sensitivity to the
old stellar population which dominates the mass. The observations were
executed as scheduled, and no anomalies were noted.
1.7 Completed NIC/1/2/3 7447 (The Cosmological Evolution of Quasar Host
Galaxies)
The Near Infrared Camera (NIC One, Two, and Three) was used to make
observations of galaxy PKS1524-13 as part of a survey to study the
cosmological evolution of galaxies which host quasars. Other point spread
function observations were taken to test the calibration of the cameras.
The observations were executed as scheduled, and no anomalies were noted.
1.8 Completed WF/PC-2 6253 (Pure Parallel Archive Program)
The WF/PC-2 was used to execute a pure parallel program taking
ultraviolet observations running concurrently with prime science
observations. The intent is to search for extra-galactic sources with flux
excesses at 3000 A0 and galactic sources with excesses at 1600 A0. The
observations were completed as planned, and no problems were reported.
1.9 Completed Three Sets of STIS/CCD 7727 (STIS Non-Scripted Parallel
Archive Proposal)
The Space Telescope Imaging Spectrograph (CCD) was used to obtain
parallel slitless spectroscopy with the G750L grating to search for
emission line galaxies at intermediate to high redshift. Field galaxy
surveys have shown that at
high redshift most galaxies have strong emission lines, and are compact and
blue. The observations were completed as planned, and no anomalies were
reported.
1.10 Completed Two Sets of WF/PC-2 6818 (The Atmosphere of Uranus:
Vertical Aerosol Structure and Horizontal Inhomogeneity)
The WF/PC-2 was used to make observations of the planet Uranus in
order to study the vertical aerosol structure and horizontal inhomogeneity
of its atmosphere. Evidence is emerging that the atmosphere of this
distant gas giant may be beginning to undergo interesting changes as the
planet moves away from southern summer solstice in 1986 toward equinox in
2007. The observations were executed as scheduled, and no anomalies were
noted.
1.11 Completed NIC/1/27775 (NICMOS Earth Flats)
The Near Infrared Spectrograph Multi-Object Camera (NICMOS) was used
to make Earth flat calibration observations. This proposal obtains a
series of Earth flats for a subset of narrow-, medium-and broad-band NIC 1,
2 and 3 filters. These flats will be used to generate the master flats for
narrow-band filters and to determine the OTA illumination pattern as a
function of wavelength and camera. The observations were completed as
scheduled, and no problems were noted.
1.12 Completed WF/PC-2 6794 (Proper Motions of Herbig-Haro Jets)
The WF/PC-2 was used to make observations of the Herbig-Haro object
HH1-2 in order to measure the proper-motions of these high Mach number
flows of its two opposing jets. The tangential velocities of several
hundred km/s will produce displacements between our first- and second-epoch
images of 2-4 pixels after only two years. The observations were completed
as planned, and no anomalies were reported.
1.13 Completed WF/PC-2 7377 (Dwarf Elliptical Galaxy Snapshot Survey II)
The WF/PC-2 was used to make observations of the dwarf elliptical
galaxy FCC173 as part of Snapshot Survey II. This survey will provide
important information on the globular cluster systems of such galaxies and
the properties of their cores and nuclei. The observations were completed
as planned, and no anomalies were reported.
